#001013

General Information about #001013

The hex color #001013, also known as Blue Charcoal, is a very dark shade of blue-gray. It belongs to the family of neutral colors and is characterized by its low saturation and luminance. In the RGB color model, it is composed of 0% red, 6.27% green, and 7.45% blue. Its primary characteristic is its near-black appearance, making it suitable for creating subtle and understated designs. The color evokes a sense of depth, mystery, and sophistication. Its dark nature makes it a poor choice for primary text or interactive elements due to accessibility concerns regarding contrast ratios against lighter backgrounds. Historically, colors like these were difficult to achieve in textile dyeing, often requiring multiple dye baths to reach such a deep, rich tone. The name "Blue Charcoal" accurately describes its dark, smoky hue.

The hex color #001013, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very dark) results in poor contrast against most background colors, including white. According to WCAG guidelines, sufficient contrast is essential for readability and usability. Text or interactive elements using #001013 on a white or light-colored background would likely fail accessibility standards. To improve accessibility, it's crucial to pair #001013 with much lighter colors to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatives include using #001013 sparingly, increasing the font size and weight when used for text, or opting for brighter, more contrasting colors altogether to ensure a better user experience for everyone.
